"I installed this on a go kart for my kids. I needed to modify the mount slightly to miss the oil fill on my motor but everything else bolted up great. Now the go kart can be operated slowly and have enough power to climb hills. If you give it gas it will still go fast as well. Works great."

"One of the strongest clutch systems I have ever used. It has a long life and is dependable. It is very easy to install and requires very little maintenance. I would recommend it to anyone that needs a variable speed clutch system."

"i have purchased two of these torque converters in the past for go karts and they have had tremendous power over centrifigul clutches. this time it is going in a verry small mini bike frame with a 5.5hp honda with the intentions of beating a friend with a 50cc pit bike who thinks its the greatest thing in the world."

"This Torque Converter works wonders. I put in on a racing Briggs engine on a home made off-road go-kart I made and it has great acceleration and top end with me riding it ( over 240 lbs). We've clocked the go-kart at around 40mph. The torque converter works so much better than a regular clutch when you want an off road machine. I would highly recommend this torque converter to anyone."

"YOUR TECH DEPARTMENT HELPED ME WITH GETTING THE WORKING DRAWINGS OF THIS TORQUE CONVERTER BEFORE I ACTUALLY ORDERED IT WHICH HELPED GREATLY IN THE BUILDING OF MY REPLICA 40'S CUSHMAN SCOOTER. WHEN I DID RECEIVE THE TORQUE CONVERTER FROM YOU IT FIT PERFECTLY WITH NO ADJUSTMENTS NECESSARY. NOW THAT MY SCOOTER IS COMPLETE THE TORQUE CONVERTER IS WORKING PERFECTLY.THANK YOU AGAIN FOR GOING ABOVE AND BEYOND TO HELP ME EVEN BEFORE I ACTUALLY ORDERED YOUR PRODUCT. WOULD NEVER GO ANYWHERE ELSE FOR THE PARTS THAT I NEEDED."
